Hello,
I'm the founder of VisitorEngage, a SaaS app to help online stores increase visitor engagement and conversions. Get a feedback tab/form for your Shopify store or run real-time notifications based on visitor's behavior on the store - product being browsed, time spent on a page, referring url, location of the visitor etc.
We released Shopify app in Beta. Please take a look here https://apps.shopify.com/feedback-push-notifications
Let me know if you got any questions.
Thanks,
Jagan
